|Title:||MYCOTOXINS AND FUNGI IN WHEAT STORED IN ELEVATORS IN THE STATE OF RIO-GRANDE-DO-SUL, BRAZIL|
|Abstract:||Samples of wheat harvested from 1988 to 1990 and stored in elevators in the south of Brazil (12 Brazilian, 4 Argentinian and 2 Uruguayan) were analysed in 1990 for 14 mycotoxins: deoxynivalenol (DON), nivalenol, diacetoxyscirpenol (DAS), T-2 and HT-2 toxins, T-2 triol, 7-2 tetraol, aflatoxins B-1, B-2, G(1), G(2), ochratoxin A (OCHRA A), zearalenone and sterigmatocystin. One sample (1988 harvest) was contaminated with OCHRA A (0.04 mu g/g) and three other samples (1990 harvest) were contaminated with DON (0.40 mu g/g), DAS (0.30 mu g/g), T-2 (two samples, 0.35 and 0.36 gamma g/g) and T-2 tetraol (1.68 mu g/g). Fusarium graminearum Schwabe was found in the 1990 samples with a relative incidence ranging from 1 to 22% and predominated in Argentinian and Uruguayan wheat (1990 harvest). Fusarium dimerum Penzig (8-75%) was the main Fusarium sp. in Brazilian wheat from the 1990 harvest.|
